A gnat takes off from one end of a pencil and flies around erratically for 18.6 seconds before landing on the other end of the same pencil. If the gnat flew a total distance of 7.15 meters, and the pencil is 6.13 cm long, find the gnat's average speed, as well as the magnitude of the gnat's average velocity vector.

Answer:

Explanation:

Total distance traveled = 7.15 m and time = 18.6 s

average speed = 7.15/18.6 =0. 3844 m/ s = 38.44 cm /s

Total displacement = 6.13 cm , time = 18.6 s

Average velocity = 6.13/18.6 =0  .3295 cm/s = 3.295 mm /s.
